DBA 4000 Series Plain Rear Rotor: Jeep Grand Cherokee / Commander (2005-2010)

DBA 4000 Series Plain Rear Rotor

2005–2010 Jeep Grand Cherokee / Commander

DBA42533

Overview:

The DBA 4000 Series Plain Rear Rotor is engineered specifically for the 2005 to 2010 Jeep Grand Cherokee and Jeep Commander models, delivering reliable braking performance with an OE-style appearance. Designed for drivers who demand consistent stopping power under everyday driving and controlled race conditions, this rotor combines advanced metallurgy with innovative cooling technology to handle increased heat and stress. It offers a direct replacement solution that maintains factory fitment and finish while enhancing durability and thermal management.

Ideal for enthusiasts seeking a balance between performance and a clean, smooth rotor surface, the 4000 Series HD variant provides the benefits of high carbon alloy construction with a refined, plain rotor face that meets controlled race division requirements without compromising on style or function.

Key Features:

The DBA 4000 Series Plain Rear Rotor incorporates several cutting-edge technologies and design elements to optimize braking efficiency and longevity:

• Constructed from XG-150 high carbon alloyed iron for superior strength and heat resistance
• Thermal Stability Profiling (TSP) process to reduce the risk of warping and cracking under extreme conditions
• Patented Kangaroo Paw ventilation featuring 144 diamond and teardrop-shaped pillars for enhanced cooling
• Up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane rotors
• Smooth OE-style rotor finish ideal for drivers requiring a factory look
• Thermo-graphic paint markings (THGP) for visual heat monitoring
• Moisture-proof corrosion protection packaging to ensure product integrity during storage and shipping
• Direct bolt-on replacement with no modifications needed

Construction & Design:

The rotor is precision cast from DBA’s proprietary XG-150 high carbon alloyed iron, a material known for its excellent thermal conductivity and resistance to cracking under repeated heavy braking. This alloy composition allows the rotor to withstand the intense heat cycles generated during aggressive driving or towing. The Thermal Stability Profiling (TSP) process further enhances durability by relieving internal stresses within the rotor, minimizing the risk of deformation and extending service life.

DBA’s signature Kangaroo Paw ventilation design incorporates a series of 144 diamond and teardrop-shaped pillars that increase the rotor’s surface area and airflow. This innovative vane pattern significantly improves heat dissipation compared to conventional straight vane rotors, helping maintain optimal braking performance and reducing fade during prolonged use.

Installation & Fitment:

This rear rotor is a direct replacement for the 2005–2010 Jeep Grand Cherokee and Jeep Commander models, designed to fit perfectly without any modifications. Installation is straightforward, following standard brake rotor replacement procedures. The rotor’s OE-style finish ensures compatibility with factory brake pads and calipers, maintaining proper braking system function and appearance.

What's Included:

• One DBA 4000 Series Plain Rear Rotor (Part # DBA42533)
• Moisture-proof corrosion protection packaging
• Thermo-graphic paint markings for heat monitoring

Ideal For:

This rotor is ideal for Jeep Grand Cherokee and Commander owners who want a high-quality, durable rear rotor that offers improved heat management and longevity while retaining a clean, OE-style appearance. It suits daily drivers, light towing applications, and enthusiasts participating in controlled race divisions where rotor aesthetics and performance are both important.
